Customer Ratings & Reviews

I got this about a month ago and I love it! I used it once and it lasts such a long time!! It’s a bit pricey but it’s really worth the money if you plan on using it a decent amount, also it’s so sleek and thin, really easy to pack or even put in your pocket.

The Anker Power Core III portable charger is a good product. When on the go you don't have to worry about your cell phone dying. However, it's called slim and it is not and I find it heavy just another bulky item in my purse. It's the same width and length as my Google Pixel 4a cell phone and it's heavier than my cell phone. It's also a bit pricey, I broke down and purchased it only because I couldn't get you know who to ship it to the Caribbean. On the next upgrade maybe you can focus on making it lighter weight and half the size.

It feels premium and heavy.. Can charge an iphone pretty quick and hold charge for a long time. The only downside is its a little expensive. You can find off brand names for a much cheaper price. Overall 4.5 out of 5

Used this on an overnight trip to charge two Pixel 5a phones and two Garmin watches, all all from about 50% to 100%, 2-3 devices at a time. Fast charging worked great on the phones using the USB-C port. It only drained about 1/4 of the battery. It's a little pricey, but worth it.

Main use was for a heated vest. It lasted longer than we thought it would. Lasted 6+ hours on high and still had over 1/4 battery life left. Will charge my iPhone from 0-100 and still read full. A bit high on the price. But over all a good buy.

Works great. Charges my Note 20 Ultra fast than most other chargers, though a bit pricey.

There's not a lot to say about most battery packs. They're basically portable chargers for your phones, tablets, Raspberry Pi, and pretty much any other mobile device you can charge off a USB cable. Anker's weird naming scheme aside, this pack has a lot of things I like about it, and a few I don't. On the plus side, the 20,000 mAH battery is quite sizable and should have enough juice to recharge most phones and tablets at least a few times. That capacity also comes with enough weight that you wouldn't want to carry it in your pocket for any length of time ( though slipping it in a bag or pack is no problem. While the USB-C port is PowerDelivery capable ( 20W max ) the regular USB-A ports can also output 12W, far more than the regular USB spec allows. So high draw phones, VR headsets, and even a Nintendo Switch shouldn't be a problem. total power output can't exceed 3A, though, so charging multiple devices at once can be slow. When charging both my phone and tablet, the tablet reached 100%, but the phone started trickle charging after 70%. The battery can also be set to a lower power output for slower charge rates. While this might be less convenient for some, faster charging also puts more wear and tear on overall battery life and expectancy. The downside of the battery is it can only be charged through the USB-C port ( in and of itself no big deal ) but it only comes with a USB-C to USB-C cable. So if you don't already have a C cable charger, or a computer with a C port, you'll need to buy a wall charger or A-to-C cable to charge the battery pack. The other drawback is the price. For this Sense model, you pay an extra $10, and so far as I can tell, that only gives you the fabric exterior. Otherwise it looks identical to the cheaper non-Sense version. Also, despite what the Best Buy product description page says, this battery pack does NOT have a magnetic or wireless charging capabilities.
